Arts & Sciences Graduate Student Theses and Dissertations

Ventricular tachycardia (VT) is frequently associated with morbidity in patients with heart disease and can lead to sudden cardiac death, which accounts for over 350,000 deaths per year and nearly half of all cardiovascular-related deaths in the United States. Despite its status as a major public health concern, arrhythmia management strategies are severely limited in safety and efficacy. Standards-of-care include defibrillators, anti-arrhythmic drugs, and/or ablations. Implantable cardioverter defibrillators improve survival in at-risk populations but severely reduce quality-of-life and increase risks of further-declining ventricular function. Pharmacologic interventions are limited in efficacy and have dozens of off-target effects which are major sources …

Soil Nitrification Inhibition With Plantain (Plantago Lanceolata), M. E. Peterson, P. M. Fraser, C. R. Anderson, N. I. Joyce, H. G. Judson Feb 2024

Soil Nitrification Inhibition With Plantain (Plantago Lanceolata), M. E. Peterson, P. M. Fraser, C. R. Anderson, N. I. Joyce, H. G. Judson

IGC Proceedings (1977-2023)

One strategy to reduce nitrogen losses from intensively grazed forage systems is to slow the first stage of soil nitrification, specifically inhibiting the microbial oxidation of ammonium to nitrite. Plantain (Plantago lanceolata) leaves and roots are known to contain several bioactive compounds (e.g., aucubin, catalpol and verbascoside) that may contribute to this inhibition. Recent laboratory studies indicate that this inhibition occurs via consumption by grazing animals of precursor bioactive compounds in aboveground biomass and their subsequent excretion as secondary metabolites in urine and/or via active exudation from the roots. Different cultivars of plantain have been shown to impart …

Maize-Alfalfa Intercropping Promote Ecosystem Services Than Fertilized Single Crops, D. X. Tao, Y. Z. Gao

IGC Proceedings (1977-2023)

Phosphorus is a non-renewable source of fertilization, which will challenge the future of food production and cropland sustainability worldwide. Crop diversity is known to promote food production, yet its capacity to alleviate the dependence of multiple ecosystem services on non-renewable fertilization remains virtually unknown. Here, we conducted a field experiment to quantify the contribution of maize-alfalfa intercropping to support multiple ecosystem services under contrasting levels of phosphorus fertilization. We showed that unfertilized intercropping systems can support larger levels of multiple ecosystem services such as soil microbial habitat, plant-soil mutualism, nutrient cycling, and soil carbon storage compared with phosphorus-fertilized single crops. …

A Transdisciplinary Approach To Landscape Transformation Towards Perennial, Diverse, Circular Systems: Why And How, V. Picasso, C. Williams Feb 2024

A Transdisciplinary Approach To Landscape Transformation Towards Perennial, Diverse, Circular Systems: Why And How, V. Picasso, C. Williams

IGC Proceedings (1977-2023)

Prevailing agricultural systems in the U.S. are dominated by intensification through annual crop monocultures and high amounts of external inputs. Increased yields per unit of land have resulted but many undesirable environmental, ecological, and socioeconomic outcomes have co-occurred. Lack of resilience within intensified agricultural systems is a factor in these outcomes. Redesign of agricultural systems and changes in federal policy are needed to better support resilience in agriculture. Redesign for greater resilience must encourage adoption of agricultural systems that are diverse, perennial, circular, and include forages. We developed a transdisciplinary framework within a project orientation with a focus on crops …
